SNOW PLOW AND SCRAPER.

SPECIFICATION forming part of Letters Patent No. 337,561, dated March 9, 1886.

Application filed August 17,1885. Serial No. 174,6ag8. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES M. OULBERT- SON, Sn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Snow Flows and Scrapers, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a plan view of a snow plow and scraper embodying my invention; Fig. 2, a side elevation of the same, and Fig. 3 a detail view of a modification.

Likeletters refer to like parts in all the figures of the drawings.

My invention relates to snow-plows for use on railways. and more particularly to that class wherein the plow is provided with a pivoted scraper, which may be dropped in advance of the plow to withdraw the snow from the track by reversing the direction of travel of the apparatus, its object being to provide means whereby the said apparatus may be readily attached to an ordinary carin such a manner as to be removed therefrom when desired.

To these ends my invention consists in certain novel features, which I will now proceed to describe, and then specifically point out in the claims.

In the drawings I have shown my invention applied to an ordinary platform-car or gendola, A. To the forward end of this car is attached,in any suitable manner, a snow-plow, B, of any approved construction.

(3 represents a scraper supported on arms 0, which are pivotally connected at their rear ends to the car in any suitable manner. This pivoting is, however, preferably effected by attaching the rear end of the arms 0 to a shaft,

D, mounted in suitable bearings, d, on a supporting-block,E. Thisblock may be mounted near either end of the car, and is secured in position by means of stakes or posts F, which are mounted in suitable sockets, f, on the sides of the car, the said stakes surrounding the supporting-block, which projects slightly beyond the edge of the car, as shown, and holding it in position.

The scraper is raised and lowered either by means of a lever, G, attached to the shaft D,

and secured in position when desired by means of a suitable catch, 9, or it may be operated by means of a chain or rope, I-I, attached to the scraper and to a suitable Windlass, H.

The operation of my device is as follows: \When it is only desired to remove snow of inconsiderable depth, the scraper will be held in a raised or inoperative position, as shown in full lines in Fig. 2 of the drawings. WVhen a drift is encountered of sucha depth that the plow cannot be forced through the same, the plow is driven into the drift as far as possible and the scraper O allowed to drop, when by its weight, which may be very great, it will be carried down into the drift in the position shown in dotted lines in Fig. 2. The car is then withdrawn from the drift, the scraper carrying out the snow taken back to a fill in the grade, where the return of the plow will dispose of the snow if the rake is not cleared by the withdrawal of the car, and distributing it in such a manner that when the plow is again driven into the drift itcan be advanced beyond the first point by means of the removal of the snow by means of the scraper. Of course it will be understood that before driving the plow into the drift a second time the scraper will be raised either by means of the lever G or by the chain and wiudlass, and held in this position until the plow has been driven in asccond time as far possible. plowing operations will be continued until a road has been cleared through the drift.

W'hen not in use, the scraper may be turned back, so as to rest upan the car in the position shown in dotted lines in Fig. 2, where it will occupy but little space. In case the lever G is employed to operate the scraper, it will be removed in order to allow the scraper to be folded back, as just described, the said lever being detachably connected to the shaft D for this purpose.

It will be observed that by the use of the improved supportingblock, which is detachably mounted on the car and carries the scraper, the whole device may be readily applied to any ordinary platform-car, and when not in use may be removed, thus leaving the ear in its original condition.

I am aware that heretofore various trackcleaning devices have been patented in which The scraping and a scraper is employed, which may be raised when the plow is driven into the drift and then lowered to remove the snow from the drift, and I do not Wish to be understood as claiming such a construction, broadly, my present invention relating more particularly to the specific construction by means of which I attain the improvements hereinbefore pointed out.

Having thus described my inventionmhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the car A, pro vided with a suitable supporting-block removably mounted thereon, ot' the scraper mounted in suitable bearings on the supportingblock, substantially as and for the purposes specified.

2. The combination of the car A, provided with removable posts F, of the supportingblock E, held in position by the said post, and the scraper mounted in suitable hearings on the supporting-bloek, substantially as and for the purposes specified.

3. The combination, with the car A, of the supporting-block E, the scraper 0, attached to a shaft mounted in suitable bearings there in, and the lever G, detaehably connected to the said shaft to permit the scraper to be turned back on the car, as described, substantially as and for the purposes specified.
